Polyplectropus pairavatika , new species

Figures 45–47

Diagnosis: This species is similar to P. orientalis McLachlan from Malaysia ( Sarawak). The 2 species have the same uniquely coiled, spine-like dorsal paraproctal processes. The new species is easily distinguished by the more regular and vertically elongate coils projecting to the ends of the cerci, not only to the end of segment X as in P. orientalis . Moreover, the new species has simple gonopod apices, not bifid apices as in P. orientalis .

Description: Male. Body uniformly brown. Maxillary palp formula (I,II)-IV-III-V, 3rd segment of each maxillary palp originating subapically on lateral surface of segment 2. Forewing length 7.5 mm; discoidal cell and median cells closed; apical forks 1, 2, 3, 4 and 5 present. Hind wing discoidal cell open; apical forks 2 and 5 present.

Male genitalia. Sternite IX semicircular, flatter on anterior margins and on posterior margins near gonopods; tergite IX narrow, parallel-sided and obliquely directed, forming continuation of sternite IX, lateral ends each meeting at fulcrum with cercus and paraproctal complex. Segment X nearly membranous, large, nearly triangular, covered with microtrichia; membranous distally, covering dorsum of phallic apparatus. Cerci each broad at base, elongate, distally slender, as long as dorsal paraproctal process; 2 times longer than paraproctal subphallic sclerite. Paraproctal complexes fused with cerci; dorsal, sclerotized, spine-like paraproctal processes regularly coiled, slightly elongate vertically, each with distal part projecting to tip of cercus. Paraproctal subphallic sclerite bilobed in lateral view ( Fig. 45 ); apices of dorsal lobes setose; laterally visible ventral lobe forming basal sclerite and dorsal setose lobe representing left side of trough. Gonopods broad, horizontally elongate in lateral view ( Fig. 45 ), each with pointed, dorsad-directed apex; in ventral view ( Fig. 46 ) pointed mesad, with 2 additional processes subbasally and at midlength on mesal margin; median process slightly directed ventrad; subbasal process forming hump, densely covered with fine, black teeth. Phallic apparatus (Fg. 47) located dorsally in genitalia; composed of arching tube-like sclerotized phallotheca and membranous endotheca or phallicata without visible sclerites.

Holotype male: MALAYSIA: West Malaysia, W. Pahang Tea Estate , 2000 ft., 1–8.xi.1981, MV light [K. R. Truck]—( BMNH, B.M. 1981-549).

Paratype: same data as holotype— 1 male ( BMNH, B.M. 1981-549), 1 male ( OPC) .

Distribution: Malaysia (Penninsular).

Etymology: Pairavatika, from “pairavatika” in Sanscrit, meaning spiral, after the spiralling basal part of each dorsal paraproctal process.
